GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
1 Swallow-induced peristalsis is called primary peristalsis, and the peristalsis elicited by esophageal distention is called secondary peristalsis. 2  Peristaltic contractions are always preceded by inhibition that, in the case of primary peristalsis, is called deglutitive inhibition.he main function of the esophagus is to propel swallowed food or fluid into the stomach. This occurs through sequential or peristaltic contraction of circular muscle in the esophageal body, in concert with appropriately timed relaxation of the upper and lower esophageal sphincters.
